Filter by:The purpose of this study is to examine how a part of the brain called the hippocampus contributes to memory changes that occur with aging and Alzheimer's disease (AD). Memory problems are the most important early symptoms of AD. The hippocampal region of the brain may be responsible for many age- and AD-related memory disorders. This study will use magnetic resonance imaging (MRI) scans to examine the structure, chemical composition, and function of the hippocampus in participants with AD, participants with mild memory problems, participants who are healthy but are at risk for AD, and healthy volunteers. Participants in this study will undergo MRI scans of the brain. During the MRI, participants will perform memory tests to demonstrate hippocampal functioning.
This study is aimed at investigating specific pharmacological interventions in the treatment of the disruptive, agitated behavior associated with Alzheimer's patients. In addition, it is hoped that specific clinical profiles will be found to predict which treatment is most effective for these particular patients.
Dementia illness often co-exists with painful medical conditions associated with aging (e.g., degenerative joint disease, osteoarthritis, skin ulcers, back pain, headaches, cancer, or angina). While the standard practice is pain assessment for all patients, the elderly with dementia have special needs for assessment, management, and evaluation. When they are unable to verbalize pain, objective measurement of their discomfort are possible manifestations of pain. No research relates systemic pain treatment with reduction of negative problematic behaviors in patient dementia.
This study evaluates the effectiveness of a nurse-managed interdisciplinary (nursing and occupational therapy) clinic serving community dwelling dementia patients and their spouse caregivers. It is grounded in a nursing self-care model that guides nurses to identify interventions that fit with the capabilities of individual patients and compensate for their specific deficits. The occupational therapy assessment uses the Allen Cognitive Levels that identify the abilities and deficits of a particular functional level so that the strategies and approaches taught to caregivers can be tailored to the specific needs of the patient.
Preventing dementia is an important goal for our aging population. This proposal is an initial 42 months study of the effect of standardized ginkgo biloba extract (GBE) on preventing or delaying cognitive decline in people age 85 years or older (the oldest old). The study focuses on the oldest old who present a distinct advantage for primary prevention studies because of their particularly high risk for developing mild cognitive impairment (MCI), a precursor to dementia. Because this is a population that has previously been out of the mainstream for use of alternative medicine, the safety of GBE in this age group will also be tested in this study. The study is randomized, placebo controlled and double blind. Approximately 200 elderly cognitively healthy subjects will be enrolled and followed for detection of conversion to MCI. This pilot study is viewed as a necessary first step in order to demonstrate that GBE, an alternative or complementary therapy, has a disease modifying effect on the brain, distinct from a symptomatic effect. The study will test the feasibility of the randomized start design, a trial design proposed as a method for discerning brain- or disease- modifying from symptomatic effects. The magnitude of biological effect of the treatments will also be assessed with volumetric quantitative MRI, a complementary means of confirming whether there is a brain modifying effect (measured as a decrease in brain volume loss with treatment). Peripheral markers of oxidation status will measure possible anti-oxidant effects of GBE.
This study will determine the effect of 240mg/day Ginkgo biloba in decreasing the incidence of dementia and specifically Alzheimer's disease (AD), slowing cognitive decline and functional disability, reducing incidence of cardiovascular disease, and decreasing total mortality.
This study is a randomized, double-blind, placebo-controlled, fixed dose study currently being conducted on two geropsychiatric units at Western Psychiatric Institute and Clinic. It seeks to evaluate the short-term safety and efficacy of citalopram and perphenazine in the treatment of 112 patients suffering from behavioral disturbances associated with dementia. Findings from this research may directly lead to improved acute pharmacotherapy for psychosis and behavioral problems in patients diagnosed with dementia. Improved treatment of behavioral complications with reduced side effects would reduce excess disability in patients diagnosed with dementia, allowing them to be maintained in the community for greater periods of time.
The purpose of this study is to learn more about the medical problems and the genetic factors involved in a recently defined form of inherited dementia called "familial dementia with neuroserpin inclusion bodies (FDNIB)." Abnormal substances in nerve cells of patients with this disease affect brain and nervous system function, causing confusion, memory decline and impaired cognition (thinking ability). Patients also develop movement disorders and, possibly, seizures. Symptoms begin in midlife, between 45 and 55 years of age. Patients with FDNIB and family members 18 years of age or older at risk for the disease may be eligible for this 3-year study. Participants will have a medical and family history and review of medical records; interview with a medical geneticist (specialist in genetics); physical, neurological and psychiatric examinations; and the following tests and procedures: 1. Blood tests to assess general health 2. Chest and skull X-rays 3. Electrocardiogram (EKG)-record of the electrical activity of the heart using electrodes placed on the chest 4. Electroencephalogram (EEG)-record of the electrical activity of the brain using electrodes placed on the head 5. Ultrasound of the abdomen-imaging of abdominal organs using sound waves 6. Brain magnetic resonance imaging (MRI)-imaging of the brain using a strong magnetic field and radio waves 7. Hearing evaluation 8. Assessment of performance of daily living activities 9. Single photon emission computed tomography (SPECT)-imaging of brain metabolism and blood flow using a radioactive substance injected into a vein The evaluation will be done over a 3- to 4-day period. At their completion, participants will meet with a physician and a genetics counselor to discuss the clinically significant findings. Participants may be asked to return for follow-up evaluations every 6 months to a year (depending on the individual's condition) for 3 years.
To clarify the relationship of the arterial lesions to aging, define the influence of the arterial changes on the development of stroke, brain infarction, and dementia, and provide a better understanding of vascular dementia.
